Bark springtail - Entomobrya sp - Entomobrya confusa

Bark springtail - Entomobrya sp - Entomobrya confusa
LaSalle County, Illinois, USA
Originally collected under the bark of a fallen tree. The most common species I find under dry dead bark. I know I’ll need to put these under the microscope but wanted to share their unique patterning; unlike any other Entomobrya I can find photos of.

Entomobrya confusa
A very applicable name ;-)
Homidia is to be excluded given dental spines are absent.
Make some lateral shots of foot3 to check the teeth on the unguis :
1. focus on inner lamella of unguis
2. focus on lateral edge of unguis
3. focus on outer margin of unguis
In addition a shot with focus on the unguiculus.

Hmmm
So either these or the other springtails you recently identified as E. confusa is a lie ;) I'll get those shots, and if these prove to be E. confusa then I'll need to look back at the other ones because they have totally different habitus

Well
IDing specimens based on photographs is a GIGO system (Garbage In Garbage Out) ;-)
If the other were different anyway then you have to put them under the microscope as well ;-)2

Homidia sauteri
To put under the microscope : the furca. On the dentes there should be an array of spines (as in Tomoceridae). You need to dissect the furca. And possibly clear it in 10% soda (NaOH).

More images added. Dental spines are absent. For the lateral furca shots and ocelli shot I cleared the specimen with a 10% sodium hydroxide solution :)

I was thinking it looked reminiscent of H. sauteri ;) Will do!
